Nonplaying captain Lee Trevino nominated Curtis Strange and Mark O'Meara to lead off for the United States in today's opening action in the Ryder Cup in Sutton Coldfield, England. Strange and O'Meara will oppose the Spanish duo of Seve Ballesteros and Manuel Pinero in the first of four morning foursomes. Each member of the two-man team plays alternate strokes on the same ball in this competition.

An exchange of lineups by Trevino and Tony Jacklin, the captain of the British-European team, also produced these foursomes matches:

Tom Kite and Calvin Peete vs. Masters champion Bernhard Langer of West Germany and Nick Faldo of England; Lanny Wadkins and Ray Floyd vs. British Open champion Sandy Lyle and Ken Brown, both of Scotland; and Craig Stadler and Hal Sutton vs. Howard Clark of England and Sam Torrance of Scotland . . .

Jim Colbert shot a six-under-par 66 to take the lead after one round of the $300,000 Greater Milwaukee Open in Franklin, Wis. Colbert, who won this title in 1972, did not have a bogey over the 7,010-yard Tuckaway Country Club Course. Twelve golfers were two shots behind at 68.

Jack Nicklaus shot 70 and his son, Jack Jr., receiving an exemption from tournament officials, shot 80 in one of the few times a father and son have competed as professionals in a PGA tournament . . .

In Kent, Wash., Alexandra Reinhardt and Stephanie Farwig, both non-winners on the LPGA tour, share the first-round lead in the $200,000 Safeco Classic with five-under-par 67s. Rookie Penny Hammel is one stroke back.
